Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    Identification of actinobacteria from rhizosphere soils for growth promotion in tomato
    (College of Horticulture and Forestry, Dr YSP UHF, Neri, Hamirpur (H.P.), 2021-01-26) Mankotia, Radhika; Saini, Raj
    The present investigation entitled “Identification of actinobacteria from rhizosphere soils for growth promotion in tomato” was carried out during 2019-2020 with the aim to explore native actinomycetes from rhizosphere of tomato crop grown at different locations in district Kullu and Hamirpur of Himachal Pradesh. A total of 109 actinobacterial isolates were obtained using different selective media for isolation viz., actinomycete isolation agar medium, yeast malt agar medium and starch M protein agar medium and the preliminary screening of the isolates for plant growth promoting attributes (PGP) attributes was carried out. It was found that only 88.99% of the total isolates showed phosphate (P) solubilization on Pikovskaya’s agar medium and the phosphate solubilization index varied widely from 1.11 to 6.0. All actinobacterial isolates displayed growth on nitrogen free Jensen’s medium and only 5.50% isolates exhibited siderophore production. The inhibition of fungal pathogens viz. Alternaria sp, Fusarium sp, Phytophthora sp and Sclerotinia sp., was demonstrated by 28.44%, 11.92%, 15.59% and 12.84% actinobacterial isolates, respectively and four isolates (NDF-10, HMS-4, HMM-1 and HMM-4) showed inhibition against all the phytopathogenic fungi.On the basis of initial screening, only fifteen actinobacterial isolates were further evaluated and found to exhibit high P solubilization (718.16 to 1418.16 μg/ml) in National Botanical Research Institute’s Phosphate broth with tricalcium phosphate and high indole-3-acetic acid/IAA (11.56 to 21.35 μg/ml) production. Maximum P solubilization and IAA production was observed in isolate KLK-8. The production of extracellular enzymes amylase, cellulase, gelatinase, lipase and protease varied among the isolates. All the fifteen actinobacterial isolates with filamentous morphology varied in their biochemical characteristics. Screening of actinomycete isolates for in vitro tomato seed germination and growth studies in filter paper assay revealed best performance of seeds treated with isolate KLK-8 which showed a significant increase in per cent germination, root length, shoot length and vigour index over untreated control. On the basis of 16S rRNA gene sequence analysis, three promising actinobacterial isolates KLK-8, HMM-1 and HMS-8 were identified as Streptomyces tendae strain KLK8, Streptomyces sp. strain HMM1 and Streptomyces sp. strain HMS8, respectively. The present study clearly indicates that native actinomycetes exhibit promising PGP attributes and could serve as bioinoculants to achieve more sustainable and environment friendly crop production.

    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-10-22) Aanchal; Kumar, Anil
    The investigation entitled “Nutritional status of vegetable growing areas of Sirmour district of Himachal Pradesh” was undertaken to evaluate the nutrient status of the area and to work out the relationship between soil characteristics and available soil and leaf nutrient contents. For this, 50 soil sampling locations were selected randomly and 100 representative surface (0-15 cm) and sub-surface (15-30 cm) soil samples were collected during FebruaryMarch, 2020. Soil samples were then analyzed for different soil physico-chemical properties viz., soil texture, bulk density, particle density, porosity, water holding capacity, soil pH, EC, organic carbon, available macro and micronutrients. The soils of the vegetable growing areas varied from sandy loam to loamy sand in texture. Bulk and particle density exhibited an increasing trend, whereas, porosity and water holding capacity showed an opposite trend with increase in the soil depth. The soils were neutral to slightly alkaline in reaction and EC values of all the soil samples were under normal range. The overall soil organic carbon content was medium to high in status. The soil nutrient indices indicated that the soils of the study area were medium in available N and DTPA-extractable Fe, Cu, Zn and Mn, whereas, high in available P, K S and exchangeable Ca and Mg. Representative tomato leaf samples were collected from the same farmer's field from which the soil samples were collected and analyzed for all the macro and micronutrients. Leaf nutrient status showed that all the samples were in medium in total leaf N, Fe, Cu, Zn and Mn. It further showed that most of the samples were medium in total leaf P, K S, Ca and Mg. Correlation studies showed that the organic carbon content had significant and positive correlations with all the soil macro and micronutrients. The leaf contents had a highly significant and positive correlation with their respective availability in soil.

    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-12-04) Dixit; Sepehya, Swapana
    The investigation entitled “Assessment of soil health under vegetable cultivation in open field conditions of sub-montane and subtropical zone of Himachal Pradesh” was undertaken to assess the effect of vegetable cultivation on soil health and to determine the correlation among soil properties and crop productivity. For this, 45 soil sampling sites were selected randomly and 90 representative soil samples from cultivated and buffer conditions were collected during September, 2020. All the required physical, chemical and microbiological parameters of soil quality were analysed and key indicators were identified using multivariate statistical analysis for computing the soil quality index. The soils of the studied areas varied from sandy loam to loam in texture. Bulk density was found comparatively lower in cultivated conditions as compared to buffer conditions, whereas, maximum water holding capacity showed an opposite trend. The soils were neutral to slightly saline in reaction and EC values of all the soil samples were in safe limits. The overall soil organic carbon content was medium to high in status. Most of the soils were medium in available nitrogen and all the soils of studied area were high in available phosphorous, exchangeable Ca and Mg. Available potassium varied from medium to high and all the soils of the studied area were deficient in available sulphur. Most of the macro and micronutrients contents of cauliflower leaves of the studied areas were sufficient. Sulphur was deficient in most of the leaf samples of cauliflower. Negative correlations of all the micronutrients were observed with soil pH. Yield of the cauliflower crop was found to be highly significantly correlated with organic carbon content. The mean soil quality index (SQI) values in district Hamirpur, Una and Bilaspur were recorded as 0.739, 0.701 and 0.783, respectively under cultivated conditions, whereas under buffer conditions mean soil quality index (SQI) values were recorded as 0.537, 0.529 and 0.544, respectively. In the overall studied area, comparatively higher soil quality/health index was observed under cultivated conditions (0.738) as compared to the buffer conditions (0.536).

    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-10-28) Vaishali; Saini, Raj
    The present investigation entitled “Studies on plant growth promoting bacteria from jeevamrit, a liquid bioformulation” was carried out during 2021 with the aim to study the plant growth promoting (PGP) potential of bacterial isolates in jeevamrit samples collected from three sites each at two different locations (Nadaun, Hamirpur) of district Hamirpur of Himachal Pradesh. The pH, N, P and K contents of the six jeevamrit samples ranged between 4.87-7.66, 1.49-2.65%, 0.004-0.052% and 0.059-0.111%, respectively. The culturable bacterial count on nutrient agar medium varied between 1.76×107 to 10.45×107 cfu/ml of jeevamrit. Preliminary screening of 112 bacterial isolates from jeevamrit revealed 66.96, 16.96, 66.96, 8.93 and 7.14% isolates to show phosphate solubilization, potassium solubilization, nitrogen fixation, siderophore production and ammonia production, respectively. Only 63.39, 27.68, 39.29, 33.04 and 38.39% isolates displayed antifungal activity against phytopathogens viz. Alternaria sp., Fusarium sp., Sclerotium sp., Sclerotinia sp. and Colletotrichum sp., respectively. Out of 112, eighteen best isolates were selected, and none displayed hydrogen cyanide production and only nine isolates showed phytase activity. Sixteen of 18 isolates showed inhibition of all phytopathogens with maximum percent inhibition (43.75-61.44%) recorded for isolate NJA-13. The phosphate solubilization index (1.69 to 12.25) on Pikovskaya’s agar was recorded highest for isolate HJA-21. The phosphate solubilization (50.25-476.50 μg/ml) in NBRIP liquid medium containing tricalcium phosphate was found maximum in isolate JJA-8. Bacterial isolates successfully produced indole-3-acetic acid (0.15 to 27.40 μg/ml), highest produced by CJV-10. Of the eighteen isolates, only 16.67, 44.44, 38.89, 5.56 and 50% isolates exhibited amylase, gelatinase, protease, cellulase and lipase, respectively. The four promising bacterial isolates NJA-13, HJA-21, JJA-8 and CJV10 with multiple PGP traits were identified as Bacillus subtilis strain NJA-13 (Acc. No. OK036919), Levilactobacillus brevis strain HJA21 (Acc. No. OK036950), Paucilactobacillus vaccinostercus strain JJA8 (Acc. No. OK036952) and Bacillus safensis strain CJV 10 (Acc. No. OK036956), respectively, on the basis of 16S rRNA gene technology. Seed bacterization with six bacterial isolates showed significant enhancement of percent seed germination, root and shoot length, and vigour index with most isolates as compared to control. Overall, the study revealed jeevamrit as a consortium of beneficial bacteria that can be utilized as potential biofertilizers and biocontrol agents, and hence, reflects the beneficial effects of application of jeevamrit in agriculture for crop production and protection.

    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-11-20) Thakur, Saurabh; kumar, Anil
    A field experiment was conducted to study the effect of integrated nutrient management in brinjal (Solanum melongena L.) under sub-montane and low hills sub-tropical zone (ZoneI) of Himachal Pradesh at the Experimental Farm of the Department of Soil Science and Water Management, College of Horticulture and Forestry, Neri, Hamirpur (Himachal Pradesh) during kharif (2020) season in a randomized block design with eleven treatments replicated thrice. The soil of the experimental farm was sandy loam in texture, neutral in reaction (pH 6.76), medium in organic carbon, P and K (4.40 g kg-1, 16.15 and 169.50 kg ha-1, respectively) and low in available N (188.16 kg ha-1) content. The treatments consisted of control (T1), 100 % RDF (T2), 75 % RDN (IF) + 25 % RDN (VC) (T3), 50 % RDN (IF) + 50 % RDN (VC) (T4), 25 % RDN (IF) + 75 % RDN (VC) (T5), 100 % RDN (VC) (T6), 100 % RDF + Azotobacter (T7), 75 % RDN (IF) + 25 % RDN (VC) + Azotobacter (T8), 50 % RDN (IF) + 50 % RDN (VC) + Azotobacter (T9), 25 % RDN (IF) + 75 % RDN (VC) + Azotobacter (T10) and 100 % RDN (VC) + Azotobacter (T11). Surface soil samples (0-15 cm depth) were collected after the harvest of brinjal crop (kharif 2020) and analyzed for physical and chemical properties of soil viz., bulk density, particle density, porosity, water holding capacity, pH, electrical conductivity, organic carbon, available N, P, K, S, exchangeable Ca, Mg and DTPA extractable Zn, Cu, Fe and Mn using standard analytical methods. Fruit and stover samples were also collected and analyzed for nutrient content to work out their uptake and quality of brinjal fruit was assessed. The treatment comprising of 100 % RDN through vermicompost + Azotobacter (T11) registered highest plant height at 60 DAT, 90 DAT and at harvest (109.03, 119.40 and 128.53 cm, respectively), number of fruits per plant (11.29), fruit length (21.47 cm), fruit diameter (4.50 cm), fruit weight (74.1 g), fruit yield per plant (830.28 g), fruit (26.07 t ha-1) and stover yield (117.46 q ha-1) as well as benefit cost ratio (2.55). However, this treatment was closely followed by 100 % RDN through vermicompost (T6). Application of 100 % RDN through vermicompost + Azotobacter could be an appropriate integrated nutrient supply package for obtaining maximum yield, nutrient uptake, benefit cost ratio, better quality of brinjal fruits and improved soil health.

    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-10-26) Shivani; Sharma, Rakesh
    A field experiment entitled "Studies on the effect of organic nutrient sources on soil properties and yield of okra [Abelmoschus esculentus (L.) Moench] in sub-tropics of Himachal Pradesh" was conducted during kharif 2020 at experimental farm of Department of Soil Science and Water Management, College of Horticulture and Forestry, Neri (Hamirpur), Dr. YSP University of Horticulture and Forestry, Nauni, H.P. in a randomised block design with nine treatments which were replicated thrice. These nine treatments were: T1= sole application of jeevamrit @ 5 per cent at weekly interval, T2= FYM @ 10 t/ha + R.D.F (recommended practice), T3= FYM @ 10 t/ha + jeevamrit @ 5 per cent at weekly interval, T4= FYM @ 10 t/ha + jeevamrit @ 5 per cent at fortnight interval, T5= vermicompost @ 2.5 t/ha + R.D.F, T6= vermicompost @ 2.5 t/ha + jeevamrit @ 5 per cent at weekly interval, T7= vermicompost @ 2.5 t/ha + jeevamrit @ 5 per cent at fortnight interval, T8= jeevamrit @ 5 per cent + ghanjeevamrit at fortnight interval and T9= 100 per cent R.D.F where, R.D.F was recommended dose of fertilizers (NPK = 75:50:55 kg ha-1). Treatment T6 recorded increase in growth, yield and quality attributes of okra as compared to recommended practice (T2). Also, T6 recorded higher B: C ratio. Further, soil bulk density, particle density, porosity, soil pH and EC did not differ significantly with the application of different organic nutrients sources. Whereas, water holding capacity, organic carbon content, available N, P, K, S, DTPA extractable micronutrients viz., Fe, Cu, Zn and Mn and biological indicator of soil such as total viable microbial population, microbial biomass carbon and microbial biomass nitrogen were recorded higher in treatment T3 followed by T6. Yield showed highly significant and positive relationship with plant height and number of leaves indicated their importance in influencing yield. Also, yield exhibited significant and positive relationship with soil organic carbon, total viable microbial population, microbial biomass carbon and microbial biomass nitrogen which indicated their importance for nutrient turn-over and their availability to plants. The study revealed that application of jeevamrit @ 5 per cent at weekly interval in combination with vermicompost and FYM showed better results over combined application of R.D.F with vermicompost and FYM.

    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2021-04-16) Kumari, Manisha; Kumar, Anil
    A field experiment was carried out to study the effect of integrated nutrient management in pea (Pisum sativum L.) under sub-montane and low hills subtropical zone of Himachal Pradesh at the Experimental Farm of the College of Horticulture and Forestry, Neri, Hamirpur, (HP) during rabi season 2019-20 in a randomized block design with eleven treatments replicated thrice. The soil of the experimental site was sandy loam in texture, neutral in reaction, medium in organic carbon, low in available N, medium in P and K at the initiation of the experiment. The treatments consisted of control (T1), 100 % RDF (T2), VC @ 10 t ha-1 (T3), 75 % RDF + VC (T4), 100 % RDF + VC (T5), PM @ 10 t ha-1 (T6), 75 % RDF + PM (T7), 100 % RDF + PM (T8), FYM @ 10 t ha-1 (T9), 75 % RDF + FYM (T10) and 100 % RDF + FYM (T11). Surface soil samples collected after the harvest of pea (Rabi 2019-20) from each plot were analyzed for different physical (bulk density, particle density, porosity and water holding capacity) and chemical properties (pH, EC, OC, available N, P, K, S, exchangeable Ca, Mg and DTPA extractable Fe, Cu, Zn and Mn). Grain and stover samples were also collected and analyzed for nutrient content to work out their uptake and quality of pea grain was also assessed. The results revealed that combined application of fertilizers and manures significantly influenced the plant height, number of pods per plant, number of grains per pod, shelling percentage, pod yield, stover yield and seed yield and nutrient uptake by pea. The treatment comprising of 100 % RDF + poultry manure @ 10 t ha-1 (T8) recorded the highest plant height, number of pods per plant, number of grains per pod, shelling percentage, pod, stover and seed yield. However, this treatment was closely followed by the treatment receiving 75 per cent recommended dose of fertilizer + poultry manure (T7). Moreover, addition of organic manures along with recommended dose of fertilizers improved the soil health in terms of physico-chemical properties of soil
